摘要
目的:检测幽门螺杆菌细胞空泡毒素基因(H.pylori vac A)不同亚型与相关胃疾病的关系,寻找能够提示不同胃疾病结局、对不同胃疾病,特别是胃癌具有预警作用的H.pylori毒力因子标志物。方法:236例H.pylori阳性病例包括浅表性胃炎(SG)81例,萎缩性胃炎(AG)77例,胃糜烂(EG)33例,胃的非典型增生(GD)16例,胃癌(GC)29例。采用PCR扩增方法对vac A基因不同亚型进行检测。结果:AG组vac Am2亚型的检出率最高(41.6%),高于EG和GC组,差异有统计学意义(P=0.018,P=0.019)。在AG组vac As1m2亚型的检出率(42.5%)显著高于EG,GD,GC组(P=0.05,P=0.035,P=0.022),与SG组比较差异没有统计学意义。结论:vac As1m2亚型H.pylori是慢性萎缩性胃炎的毒力菌株。
